An old American dialect name for the river otter — the confusion arose because both beavers and otters were semi-aquatic mammals that burrowed into river banks, and early settlers often mixed up the terminology. A bank beaver hunted fish rather than built dams, which is the tell. The term faded once people got their mammals straight, but it's a charming piece of frontier natural history.
The trapper came back with three pelts he called bank beavers, though the fur trader knew straight away they were otters.

- native bear50%
An old Australian term for the koala, now obsolete but historically common among early European settlers who didn't know what to call the unfamiliar marsupial. The bear comparison made sense visually — round ears, stocky build, tree-dwelling — even though koalas are marsupials and bears are placental mammals. The term faded as koala became the standard, but native bear survives in historical texts and colonial-era writing.
